Wind energy and how to use it to generate electricity<\/span><\/span><\/strong><\/h2>\n
\n

A search for wind energy. Wind energy is classified as one of the types of renewable energy sources because it relies on the wind source instead of using fossil fuel sources, oil and natural gas. These sources are harmful to the environment because of the toxic gases they produce when burned, in addition to being available only in limited areas. In the world.<\/span><\/span><\/p>\n

Where the importance of using wind energy in European countries and America came to reduce dependence on traditional energy sources and reduce environmental pollution and costs.<\/span><\/span><\/p>\n

\"Wind<\/p>\n

<\/span>What is energy<\/span><\/span><\/h2>\n

Energy means (English: energy) in the science of physics the ability to do something by converting energy from one form to another to produce different forms of energy such as: converting energy into electrical, thermal, radiation, nuclear or chemical energy, whose work depends on kinetic energy or energy lurking.<\/span><\/span><\/p>\n

<\/span>Definition of wind power<\/span><\/span><\/h2>\n

Wind energy is defined as a source of transformable energy, which results from exploiting the movement of wind and converting it into another form of energy such as electricity energy, where its work relies on the movement resulting from the wind in generating electrical energy by moving wind turbines. Mechanical energy, which in turn is converted into electrical energy. Wind energy is one of the renewable energy sources, which is used as an alternative source to traditional energy sources.<\/span><\/span><\/p>\n

<\/span>uses of wind energy<\/span><\/span><\/h2>\n

Wind energy has been used since ancient times at the level of different civilizations, as the ancient Egyptians used this energy to run their boats on the Nile River in Egypt, and the Muslims used it to grind various grains, while the Chinese exploited it to pump groundwater in particular.<\/span><\/span><\/p>\n

As for the Arab countries, there are no development studies on increasing reliance on this energy to generate electricity, and the weakness of cooperation and coordination between countries has led to weak reliance on this energy and other renewable and non-polluting energy sources.<\/span><\/span><\/p>\n

      How do wind turbines work? <\/span>Wind energy is one of the ways to generate electricity, and it is classified as an environmentally friendly renewable energy resource.<\/span><\/span><\/p>\n

      In this article, we will discuss how wind turbines work, and what is the best place to place the field?<\/span><\/span><\/p>\n

      How do wind turbines work?<\/span><\/span><\/h2>\n

      A wind turbine contains rotating blades that are mounted on a shaft and a generator that converts the kinetic energy of the wind into electrical energy.<\/span><\/span><\/p>\n

      When the wind passes over the blades, it creates a dynamic air impulse that causes the blades to rotate. Thus, the generator operates, which produces electrical energy. These turbines are equipped with a device that controls the rotation of the blades to regulate their rotation rates and stop their movement if necessary.<\/span><\/span><\/p>\n

      The amount of energy produced from wind turbines depends on the wind speed and the diameter of the blades. That is why the turbines that are used to operate factories or lighting units are placed above the towers. <\/span>Because wind speed increases with height above the ground, these turbines are placed in large numbers on large areas of land to produce as much electricity as possible.<\/span><\/span><\/p>\n

      \n
      <\/div>\n<\/div>\n

      Here is an example of a field around the world. The United States alone produces about 3 billion kilowatt-hours annually, and that amount is enough to meet the electricity needs of a million people, from wind fields located in California on the west coast of America.<\/span><\/span><\/p>\n

      Where is the best place to put wind turbines?<\/span><\/span><\/h2>\n

      It is preferable to place wind turbines in a place where the average annual wind speed should not be less than 12 miles per hour, as most wind fields are located inside the water, and they are called offshore farms, as wind speeds are higher than on land.<\/span><\/span><\/p>\n

      And because there are times when the wind speed is slow, which makes it difficult to produce electricity, wind energy users must have a backup diesel or solar generator to use at those times.<\/span><\/span><\/p>\n

      Components of the wind power plant. Each generating station has its own components. The plants that depend on wind energy contain blades, a box and a turbine, while solar power plants consist of panels and inverters.<\/span><\/span><\/p>\n

      In this article, we will get a quick look at the source of wind, and then mention the basic components of wind power plants.<\/span><\/span><\/p>\n

      <\/div>\n<\/div>\n

      <\/span>A quick look at the source of the wind<\/span><\/span><\/h2>\n

      Winds are generated as a result of the absorption of sunlight by the surfaces of the earth, seas and oceans, and thus the temperature of these surfaces rises by different degrees.<\/span><\/span><\/p>\n

      When the air heats up, this leads to a decrease in its density, and accordingly, the air moves from the high pressure area to the reduced pressure area, which leads to the emergence of winds.<\/span><\/span><\/p>\n

      Windmills have spread since the twelfth century until their number reached in the year 1750 AD to more than 8,000 mills in the Netherlands, and more than 10,000 mills in England,<\/span><\/span><\/p>\n

      The main purpose of its work at the time was to pump water from low areas to higher agricultural areas, or to manage stones for grinding wheat, corn, and other grains.<\/span><\/span><\/p>\n

      <\/span>Components of a wind power plant<\/span><\/span><\/h2>\n

      The generating fan consists of the following elements:<\/span><\/span><\/p>\n

      <\/div>\n

      <\/span>Turbine blades<\/span><\/span><\/h3>\n

      The blade length reaches 20 metres, and in newer variants such as the 5-mega unit, the turning radius exceeds 130 metres.<\/span><\/span><\/p>\n

      <\/div>\n

      <\/span>Gearbox<\/span><\/span><\/h3>\n

      Gears connect:<\/span><\/span><\/p>\n

        \n
      • The slow speed transducer on which the blades are mounted, rotates at about 30 RPM.<\/span><\/span><\/li>\n
      • The high speed shaft is the one that connects directly to the generator and rotates at a speed of 1500 rpm.<\/span><\/span><\/li>\n<\/ul>\n

        <\/span>Cabin Room (Nacelle)<\/span><\/span><\/h3>\n

        It includes the generator and the gears, as it is the housing for all the equipment, and it also includes the equipment that controls the vanes (blades), as it can change the inclination angle of the vane with respect to the wind by means of a motor, and thus controls the rotational speed, which in revolutions per second is affected by the wind speed, which must not be less than 5 meters per second, and it should not exceed 30 m\/s.<\/span><\/span><\/p>\n

        <\/div>\n

        <\/span>Generator<\/span><\/span><\/h3>\n

        The generator capacity ranges from 500 to 1500 kilowatts, and some generators have now reached 3, 5, 6, 7 megawatts, and more.<\/span><\/span><\/p>\n

        Power transmission transformer<\/span><\/span><\/p>\n

        The transformer of the unit transmits the power with a distribution voltage of about 24 kV through cables, and it is assembled with the other units, and then lifted to the transmission lines, and each unit is not connected directly with the transmission lines.<\/span><\/span><\/p>\n

        <\/div>\n

        <\/span>maternity tower<\/span><\/span><\/h3>\n

        All equipment except the transformer is installed at the top of the generation tower, which is made of steel and has a height of 40 to 60 meters, and at the present time the height exceeds 140 meters, with capacities of 5 mega.<\/span><\/span><\/p>\n

        The tower is made of heat-treated iron to bear all the components of the container, which weighs up to 30 tons.<\/span><\/span><\/p>\n

        To ensure the maximum possible use of wind energy, a system is used to direct the turbine in the direction of the wind. If the wind speed rises above 25 meters\/second, the brakes prevent the blades from rotating, lest the high wind speed lead to their shattering and breaking of the rotating parts in the container.<\/span><\/span><\/p>\n
